1 01mm. (o1- 5 2 Thisinvention relates-to bed springs, and is' an improvement over the construction embodiedin my prior Patent No. 2,271,388,.issued January 2'7, "19.42.

Anobject of this invention is toprovide a bed spring structure which includes a supporting frame, a spring frame, and suspension springs between the frames ,so'as to absorb a portion of the weight, thereby permittinglighter springsin the .spring frame section so asto thereby provide increased cushioningeffect. ,rAnother object of this invention is to provide an improved bed spring structure wherein the mattress will be seated within the suspension frameso that the mattress will beheld against lateral and longitudinal shifting.

. ,i-Ajurtherobject of this invention is to provide a'sc'tional bedspring structure wherein'the movdrawings and specification, and then ,more particularly pointed out in the appendedclaimI In'the drawings,

Referring to the drawings and first to Figures r toilfli lus v t amlme a designates e lly s pens n Q s p ort n frame whic is adapted to be engaged with the longitudinal rails of abedst ead. Thesuspensionframe 15 is formed :of apair of parallel side rail members [6, angleshapedin transverse section, and also includes head and foot angle bars I! and 18 respectively. The side rails l6 are connected to the head rail I Lbyv means of a right angle connecting member is forrned of angle iron, and the rails I6 and I1 together with the connector I!) are'formed with a plurality of spaced openings 20 through which bolts 2| are adapted-toextend and wing nuts 22 are threaded onthe bolts 2|. The rear ends 'of the side rails I'BarecOnnected to theiootrail or r bar l8 by means of right angle connecting members23 which are similar to the connecting members I9. Wi'ng nuts,22 are threaded on bolts 2| for securing the connectors 23 to the rails or bars l6 and I8.

-By providing spaced openings between theside ,railsand theendfrails .with spaced openings in theright angle'connectors, the suspension frame may beexpanded or contracted bothflongitudi- .nally and laterally so that it' will correctly fit the bedstead; It will be understood that the length- LwiseL-and lateral adjustment of the suspension frame ,-l5' will beonly very. slight butby having this suspension frame lengthwise and laterally adjustable as to size, thesuspension frame can be adjusted .to fiti'anycon'ventional size of bedstead; .It'is of course, understood that bedsteads ,are ,fracti'onally" different one from the other 'so .thatthe adjustmentof the suspension frame will be. only'a slight adjustment." 3

The suspensionfrar'ne l5 has dependinglysecured thereto a spring framefgenerally designated as 24. {The pring"rramejgzai includes a lower rectangular frame 25 which is yieldably suspended from the upper frame-l5 by means of a plurality of vertically disposed suspension springs 26. The lower frame 25'has extending transversely thereacross a plurality of spaced parallel T-shaped spring seat bars 2'! which are disposed in inverted position. An upper rectangular frame angularly disposed pairs. The outermost ones of.

the springs 29 are connected to the frame 28 by relatively short connecting members 35 whichare similar to the connecting member 35shown in Figure 9.

The spring structure herein disclosed includes an open box or compartment structure 3:: forming the foot section which includes a hinged closure 31. A head section 38 is connected with the spring frame 28, extending coplanar with the frame 28 and coupled with the lower frame 25 by means of extensible'bars 39.

Referring now to Figure 11 there is disclosed a modified form of spring for use with the spring structure 24. A double spring 40 is provided of spiral configuration with the small ends of the spring innermost and secured to an intermediate frame 41. The intermediate frame 41 provides a means whereby the spring 40 will not collapse laterally as weight is applied to the upper end thereof. 7 Referring now to Figure 12 there is disclosed another modified form of spring structure embodying two spiral coil members 42 disposed with their large ends uppermost and an intermediate frame 43 is disposed between the spring sections 42 so as to prevent collapsing of the springs under a weight applied to the upper one of the two springs.

Referring to Figure 8 there is disclosed the suspension frame is which is adapted to be substantially completely covered witha rubber or latex jacket 44 so that no metal will contact with the bed rail 45. In Figure 7 there is disclosed a rubber jacket or sheath 46 about the T-bars 21 and in this instance the jacket or sheath 39 is open as indicated at 4] on the lower side of the T 21. As will be noted from Figures 2 and 3, the

upper frame member 28 of the spring frame together with the upper ends of thehead and foot sections are disposed a substantial distance below the suspension frame 15, thereby providing a space within which the mattress is adapted to engage. Themattress when seated on the top of the spring structure 24 will be held against both lateral and longitudinal movement relative to v the suspension frame l and to the bedstead.

The crossed tie straps 33 are used as a substitute for the steel crossed helicals which are usually used with springs and will eliminate the scraping noise usually caused by the steel helicals.

By providing a bed spring structure as herein before described, the movable and immovable parts thereof covered with rubber or latex, the spring will not squeak and will also be substantially vermin proof.

Ido not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.

What I claim isz In a bed spring structure including a lower rectangular frame, and serried longitudinally and transversely spaced apart coil spring members extending upwardly from said frame; crossed connecting members extending diagonally between the upper ends of said coil spring members and formed of a resilient rubber material, each of said connecting members including an elongated flattened central portion and arcuate tubular heads of circular cross section having their concave sides facing outwardly of said central portion on the opposite ends of said central portion the concave sides of said heads being longitudinally split to engage about a portion of the top coil of said coil spring members, each arcuate head having a radius of curvature equal to that of the top coil of said coil spring members and a length of approximately of arc of the circle of said top coils.
